Fix: Add 'include-hidden-files: true' to actions/upload-artifact@v4 step in execute-actions-importer job

[porschedetto]

In the current version, the dry-run command is broken. The Workflow triggered by the issue is only posting a comment with an empty reference on the generated worfklow .yml file (see screenshot).

Here is what I've discovered:
If the command gh actions-importer dry-run gitlab is executed in the step “execute actions-importer” as part of the job “execute-actions-importer”, a GitHub .yml workflow file is stored under the path output/<GITLAB_TLG>/<GITLAB_PROJECT>/.github/workflows/<GITLAB_PROJECT>.yml.

This file cannot be uploaded in the following step “Run actions/upload-artifact@v4” because the with-attribute include-hidden-files was introduced in Release 4.4.1, which is set to false by default ignoring hidden files. Since the path structure contains /.github, the generated worfklow .yml file is treated as hidden file, ignored by the action step, not uploaded and therefore not consumable in subsequent jobs such as dry-run.

As a simple fix, I suggest adding an include-hidden-files: true to the actions/upload-artifact@v4 job at this step in the file .github/workflow/issue_ops.yml. With this adjustment the dry-run job works again, otherwise
